There are a considerable number of references to the king in the complete calendar under consideration, and we are permitted to assume, therefore, that the calendar served as a further guide for the priests in their instructions to the king. The allusion to oracles, curses, and weapons points in this same direction, and when, as in a number of instances, a day is described as one on which Shamash or some other god is 'angry,' it is in all probabilities against the ruler rather than against private individuals that the god's displeasure has been manifested. A similar official and public character is borne by another calendar, where months alone are indicated and their significance interpreted.[623] The twelve months are arranged in as many columns. Under each column the indications 'favorable' or 'not' are entered, while at the right end of the tablet the specifications are added for what undertakings the month is, or is not, favorable. One of these specifications is "the soldiery to make an attack upon a hostile city," and upon referring to the list of months, we learn that the 2d, 6th, 7th, 8th, and 12th months are favorable for such an undertaking, but the others are 'not.' Again, the 1st, 3d, 4th, 6th, 8th, 9th, 10th, and 11th are 'favorable' for "the entrance of any army upon foreign soil," but the remainder 'not.' The other specifications refer likewise to the movements of the armies. Such a calendar was evidently drawn up on the basis of omens, for a specific purpose, and, we may add, for some specific expedition to serve as a guide to the military commander. In the same way, calendars were drawn up devoted to indications regarding crops and for other purposes of public interest. To a more limited extent, private affairs are also touched upon. To enter upon a further discussion of details is unnecessary at this point, and would carry us too far from the main purpose of this chapter, which is to point out the diverse ways in which the belief in omens is illustrated by the religious literature of the Babylonians.
